DRY CLOSET.

SPECIFICATION forming part of Letters Patent No. 384,932, dated June 19l 1888.

(No model.)

To @ZZ whom it may concern:

Beit known that LLUCIAN B. Rose, a citizen of the United States of America, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Dry Closets, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to the peculiar' construction of crematingcloset secn in Letters Patent No. 376,550, granted to me January 17, 1888; and the present improvement consists in providing the deposit-chamber with a ilue or tlues whose discharging end communicates with the furnace and near the front ofthe same, in order that all offensive gases, vapors, 85e., generated within said chamber may be discharged into said furnace, so as to be consumed when the closet is tired up, as hereinafter more fully described.

In the annexed drawings, Figure 1 is a vertical section of my improved closet, said section being taken at the line 5 5 of Fig. 3 and looking toward the diving-flue F. Fig. 2 is a similar sect-ion taken at the line 6 6 and looking toward the furnace B. Fig. 3 is another vertical section, said section being taken at the line 7 7 of Fig. 2 and looking toward the rear of the closet. Figli is a horizontal section taken at the line 8 8 of Fig. 1.

Arepresents the outer walls of the structure, and B is the furnace, which furnace is preferably covered with an arched casting, C, having horizontal fianges c o', resting upon the side walls, D D', of said furnace. Furthermore, this casting has in front a horizontal extension or plate, E, beneath which openings f f arelo cated,which openings communicate both with the furnace B and the diving-fines F F, said iues being carried up almost to the top ofthe depositchamber G.

H is afire-door at the front of the furnace, and I is a chimney at the rear of the closet.

J is a soil-pipe for conducting excreta, sewage, and other waste substances into the cham ber G, to which latter access is afforded by t-he door K. l

L L are pits formed between the sidewalls, D D', of the furnace and the outer walls of the structure, said pits being filled with a nonconibustible absorbent-bed, M, (seen in Fig. 2,) the level of said beds bei ng indicated by the dotted lines m m in Fig. 3. This closet is man-` aged in practically the same manner as the apparatus seen in my patent previously referred to-that is to say, the doors H K are normally closed and the waste substances are' dropped down the soil-pipe J and gradually accumulate within the deposit-chamber G, the gravelbeds M absorbing the fluids and thereby separating the latter from the more solid portions of the sewage.

When the deposit-chamber is filled about as high as the dotted line g,(seenin Figs. 1, 2,and 3,) the lower door, H, is opened and a fire is then started in the furnace B for the double purpose of evaporating the iluids from the absorbent-beds and initiating the drying of the solid contents of said chamber. starting this fire the privy-seats or other inlets attached to the soil-pipe .I must be securely closed, in order that all vapors gener"-W Previous to` F or F', which iues may 'in some cases be on the outside of the structure. These flues draw off the foul vapors from the upper part of the chamber, as indicated by the arrows in Figs.` 1 and 3, the gases, Src., being conducted down said flues to the openings ff and thence.

through the latter, into the furnace B. Here the gases are brought into intimate contact with the mass of incandescent fuel in the furnace and are at once completely consumed, the vapors escaping from the chimney or other exit I being free from any offensive or noxious odors.

It will thus be apparent that the present` closet is automatically ventilated, and on this account it can be burned out in the summer season without creating a nuisance in the` IOO a aawsz different parts o' the closet have not been ad` furnace B, diving-lines F F', openingsff, dehered to, the furnace being considerably longer posit-chamber G, doors H K, exit IJ inlet J, than is illustrated either in Figs. l or 4. and pits L L', which latter are Charged with a I5 I elaim as my inventionnon-oombusfible absorbent-bed, as M, for the 5 1.
